I agree will all of this and your previous post too. In my yard we fix lots of problems with cored boats. Personally I would not want another cored boat. (except for maybe the deck). Balsa rots, foam comes apart. All the "advantages" go away with time. We have worked on one fully cored long rage trawler that is so rotten in the core that picking it up with the hoist is like trying to pick up a rotten tomato with with a toothpick. Built for long offshore trips? I don't think so. I wouldn't trust it on a rough day on the lake. And you can't really fix it. It's now junk. Speed, stiffness etc. etc.- I don't believe this construction would be so popular unless it was significantly cheaper than solid glass. Todays' boats seem to be designed and built for the magazine "boat tests" lol, and the sales brochure. From what I see many many pleasure boats spend 90% of their time sitting at the dock and really don't get run very hard or very often. The boat builders have probably seen this too. Their job is to survive and sell boats. Their market research probably tells them that granite countertops and goofy looking curved hardtops sell more boats then a seaworthy hull does. So, they can build 'em cheaper and sell more. In a way you can't blame them. Ok maybe you can.
